I am running Gnome 3, this application is on the desktop yet when I try to run it nothing happens, what is it.
Never used it myself as I dislike gnome, but …
Gnome CD Master is a GUI frontend for creating audio CDs and burning them using cdrdao.
Taken from: GCDMaster Homepage
As to why it doesn’t run, have you tried running it from a terminal so as to get some feedback on why it won’t open?
